BLANCHE A. STONE, OF ROCHESTER, NEW YORK.

WASHING-MACHINE.

Application filed December 27, 1915.

To all whom it may concern:

Be it known that I, BLANCI-IE A. STONE, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Washing-Machine, fully set forth in the following specification and shown in the accompanying drawings.

The present invention relates to washing machines and more particularly to the type in which a washer head is caused to act upon the clothes within a suitable receptacle, an object of this invention being to provide for supporting the washer head in such a manner that its field of operation is such that it may be made to. operatein different portions of the washing receptacle or, in fact, in different washing receptacles without any readjustment of the machine. A further object of the invention is to provide for supporting a washer head upon a wash tub in such a manner that the attachment and detachment of the machine may be quickly efl ected and yet the parts, while in operative position, are firmly held in place. A still further object is to provide a construction adapted to be attached either to a wash tub or to any other suitable support.

To these and other ends, the invention consists in certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings:

Serial No. 68,674.

Referring more particularly to the drawings, 1 indicates a receptacle which, in this instance, is in the form of a metallic tub. In order that this tub may be used effectively without splashing water and suds therefrom, it is desirable to employ a shield which preferably is in the form of an open-ended ring 2 having an annular bead 3 at its upper edge and a reduced lower portion at forming a surrounding shoulder 5 which rests on the upper edge of the tub when the reduced lower portion of the shield is inserted within the tub. To protect the bottom of the tub, a plate 6 is employed preferably formed with perforations 7 and spaced from the bottom of the tub by bands 8. This false or supplemental bottom plate permits the circulation of water therethrough thus assisting in the washing action.

The tub preferably forms a support for the operating mechanism and, to this end, there is provided an attaching frame comprising preferably two members 9 and 10 adjustably connected together in any suitable manner but preferably by bolts 11 on the member 10 operating in a slot 12 formed in the member 9, the bolts being. engaged by thumb nuts 13 thereby providing a quick or coarse adjustment between the members 9 and 10. The member 10 may carry a receptacle-engaging portion 14: which is arranged on the end of the thumb screw 15, the latter being carried by an arm 16 on the slide 17, the slide being guided on ways 18. For effecting the movement of the slide on the ways, the latter may be provided with a transverse slot 19 while the member 10 is provided with a curved slot 20 intersecting the slot 19. l/Vithin both of theseslots, a bolt 21 operates having preferably a thumb nut 22 thereon and this bolt may be mounted on a swinging member 23 which is pivoted at 24 to the outer face of the member 10 and carries an operating portion 25. By moving the member 23, the bolt 21 moves in the two slots 19 and 20 and effects the movement of the member 17 on the ways 18, thus providing a fine adjustment for the tub engaging member 14.

The member 9 may also carry a tub-engaging member in the form of a hook 26 which is rigid with the member 9 and is adaptedto engage the upperend. of the,

tub 1, the shield being provided with a notch 27 in order to receive this hook. The member 9 also has an upright extension 28 which forms a support for the operating mechanism.

As shown in Fig. 1, the member 28 is engaged by a bracket 29 which is bolted to the support 28 by bolts 30. This bracket has projecting from one face thereof, two lugs 31 formed with alined bearing openings 32, the upper faces of these lugs being formed with radial notches or recesses 33. For cooperation with these bearing lugs, there is is provided a swinging frame 34 having alined bearing pintles 35 received within the bearing lugs 31 and held therein by cotter pins 36 or other suitable means. Projecting laterally from these bearing pins are studs 37 which are adapted to be received within the notches 33 for holding the frame 34 in different positions against free swinging movement, the cotter pins being slightly spaced from the lower sides of the bearings 31 in order that the frame 34 may be elevated to cause the projections to engage in anyone of the notches or recesses 33. This permits the frame 34 to lie in the position ShOWn in Fig. 1 or in two positions at right angles to such position in order that the washer head may be carried inwardly toward the supporting bracket 29. The frame 34 may be provided with an eye 38 which receives a hook 39 on the end of a lever 40, the free end of this lever being provided with a hand grip 41. The lever is held in the position shown in Fig. 1 by a coil spring 42 anchored at 43 to the lever and adapted to be connected at its other end to any one of the hooks 44 on the upright portion 45 of the frame 34. It is apparent that by connecting the spring 42, to the frame upright 45 at points below that shown in Fig. 1, the tension of the spring will be decreased.

Pivotally connected at 45 to the lever 40, between the hand grip and the pivot of the lever, is a stem which preferably embodies a head portion 46 having a tubular casing 47 rigid therewith and inclosing a helical spring 48 which bears on the enlarged upper end 49 of a socket member 50 in which is removably secured bv a pin 51, the upper end of a rod 52. The lower end of this rod is removably secured by a pin 53 to the socket 54 of the washer head, the construction of which will be hereinafter described.

If desired, the frame 34 may be removed, and the lever 40 connected directly to the upright portion 28 of the attaching frame as shown in Fig. 2. To this end, the spring 42 is directly connected to the hook 55 at the upper end of the supporting member 28 and the hook 39 is engaged within an eye 56 formed in one end of a member or frame 57 that is mounted to slide in an opening 58 in the support 28. This construction increases the field of operation of the washer head merely by moving the lever 40 in the direction of its length.

In other instances, I have found it desirable to pivot the lever 40 directly to the support 28 and to this end, I provide the lever with an opening 59 which is adapted to receive a laterallyextending bearing member 60. With such an arrangement, the lever 40 may have the spring 42 connected in the manner shown in Fig. 2. 4

In still other instances, it is desirable to mount the spring 42 in rear of the washing receptacle and, to this end, the hook 39 is carried by a detachable cap 61 in order that the lever 40 may be fitted in a socket member 62, this socket member having a rearwardly-extending arm 63 connected to one end of the spring 42, the other end of the spring being anchored at any fixed point below the lever 40. The socket member is also pivoted at 64 to a bracket 65 which is removably secured by a bolt 66 to a rearward extension 67 on an arm 68 which extends laterally from the member 9.

The washer head preferably is in the form of a hollow cone 69 into the smaller end of which the stem socket 54 projects. The interior of this cone is divided into a plurality of chambers commuicating one with another. The uppermost chamber 70 may be formed by an inverted truncated cone-shaped member 71 which is heldin place by rolling the lower edge 72 of the socket tube 54 over the lowermost edge of the cone-shaped partition 71. The next chamber 73 may be formed between the partition 1 and a horizontal partition 74 while the next chamber 75 is formed between the horizontal partition 74 and a partition 76 which has a concavo convex central portion 77, the convex side being disposed toward the larger end of the cone 69. Below the partition 76, the largest and lowermost chamber 78 is formed. The chamber 78 communicates with the chamber 75 by openings 79 in the partition 77 and the chamber 75 communicates with the chamber 73 by openings 80 in the partition 74, while the chamber 73 communicates with the chamber 70 by openings 81 in the partition 71. The chambers 78, 75, 73 and 70 decrease in size in the order named.

Arranged on the exterior of the coneshaped member 69 are a number of channels or passageways 82 which gradually increase in width from the upper end of the cone 69 to the extreme lower end thereof, these channels 1n this instance being formed by curved strips of metal 83 secured to the exterior channels or passageways are provided with openings 85 near their lower ends, these openings being relatively smaller than the openings 84.

The theory of the operation of this head is that the air, which is trapped in the head, will be discharged from the successive chambers into the channels 82 and will issue from the lower ends thereof with great force, its place being taken by the water. On the upward stroke of the head, the water will attempt to leave the head andin doing so will create a partial vacuum therein, thus producing a lifting action on the water, but this will not be permanent as the vacuum will be destroyed by air passing through the openings 85 and also by air passing through the clothes by way of the open ends of the channels 82.

In using the machine, the receptacle 1 is filled with clothes and water with suitable cleaning or bleaching ingredients therein, while the operating mechanism is clamped to the tub or receptacle in the manner shown in Fig. 1 with the handle 40 connected to the supporting frame as shown in Fig. 1 or as shown in Figs. 2, 3 or 4. When the handle L0 is vibrated about its axis, the aerating head is raised and lowered and produces the action previously set forth. The spring 42 assists in bringing the head to normal position thus taking part in the lifting action. The frame 34 permits the operating handle 40 to be shifted so that the field of operation of the head may be changed. In fact, it is possible with this construction to operate in two or more tubs or receptacles arranged one beside the other. The bracket 29 may be disconnected from the attaching frame and secured to any other support. It is apparent that any desired number of washing heads may be secured to the stem which is supported by the pivoted lever. The washing head causes a violent agitation of the Water making it to pass through the clothes. Furthermore the water is saturated with air which also passes through the clothes during the agitation.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a washing machine, an attaching frame, two tub engaging devices carried by said frame, a slide mounted on said frame and carrying one of said tub engaging devices, the frame and the slide being provided with intersecting slots, and a pivoted lever mounted on the frame and carrying a portion operating in said slots to effect the adjustment of the slide.

2. In a washing machine, the combination with a supporting member, of a frame mounted to turn on said member about an upright axis, means for holding said frame against swinging at different points about its axis of turning, a lever having a swinging connection with said frame to move both vertically and horizontally on said frame, and a washer head carried by said lever.

3. In a washing machine, the combination with a supporting member having a bearing lug formed with a vertical bearing and with notches disposed radially with relation to said bearing, a supporting frame having a bearing turning in the bearing of the supporting member and carrying a projection adapted to enter any one of the notches, a lever having a swinging connection with the frame to move both vertically and horizontally on said frame, and a washer head carried by said lever.

4. In a washing machine a supporting member having two lugs formed with alined bearing openings, a swinging frame having bearing pintles received within said openings and an upright portion on said frame at the free end of the latter, an eye being arranged at the base of said upright portion, a lever having a hook at one end engaged in said eye to permit the lever to swing up and down or sidewise, a stem pivoted to said lever to swing only in the plane of said lever, a washer head carried by the lower end of said stem, and a spring connected to the upper end of the upright and to the lever.
